The equipment lease-versus-buy decision for contractors, run with 2026 numbers, including the tax trap that looks like a win. Reference content for Florida trade business owners. Reviewed against IRS sources, 2026.


Every December, a version of the same conversation happens in contractor offices across Florida. Profits look good, the tax bill looks worse, and someone says: let us buy a piece of equipment before year-end and write the whole thing off. Section 179 makes that possible, and it is a genuinely powerful tool. It is also the fastest way to convert a tax problem into a cash problem, if the decision is made for the deduction instead of the business.

Here is how Section 179 actually works in 2026, where the lease-versus-buy math really lands, how it stacks with bonus depreciation, and the trap that catches contractors who chase the write-off.

Quick Answer: Should You Buy Equipment for the Section 179 Deduction?

Section 179 lets a business deduct the full cost of qualifying equipment in the year it is placed in service, rather than depreciating it over years. For 2026 the maximum deduction is $2,560,000, phasing out once purchases pass $4,090,000 (IRS Rev. Proc. 2025-32). The deduction is real, but it is not cash: a $100,000 purchase at a 24% rate saves about $24,000 in tax while $100,000 leaves your account. So the question is never “do I want the deduction,” it is “does the purchase make sense before the deduction.”

Section 179 tends to help when Section 179 tends to hurt when
You needed the equipment for the work anyway You are buying mainly to lower a tax bill
Your taxable income is high enough to absorb the deduction A thin year leaves too little income to use it
Cash reserves are strong, or financing protects your cash Paying cash in December strains winter payroll
You will keep the equipment in the business long-term Use may drop below 50%, triggering recapture

If the purchase only makes sense because of the deduction, that is the signal to stop. The sections below show the lease-versus-buy math, the ordering rule with bonus depreciation, and the timing traps that quietly undo the plan.

What Section 179 Does in 2026

Section 179 lets a business deduct the full purchase price of qualifying equipment in the year it is placed in service, instead of depreciating it over five or seven years. For tax years beginning in 2026, the maximum deduction is $2,560,000. It begins to phase out dollar-for-dollar once total qualifying purchases exceed $4,090,000, and disappears entirely at $6,650,000 (IRS Revenue Procedure 2025-32; these limits were raised substantially by the One Big Beautiful Bill Act and are adjusted annually for inflation).

For a trade contractor, almost everything you buy qualifies: trucks, trailers, heavy equipment, tools, off-the-shelf software. Certain improvements to nonresidential buildings, including roofs and HVAC, security, and fire-protection systems, also qualify. Two conditions matter most. The equipment must be placed in service during the tax year, not just ordered or paid for, and it must be used more than 50% for business.

Vehicles carry their own caps. Heavy SUVs between 6,000 and 14,000 pounds GVWR are limited to a $32,000 Section 179 deduction for 2026, and vehicles under 6,000 pounds follow ordinary, much lower depreciation limits. The work truck a contractor actually uses on jobs usually qualifies broadly; the large SUV that doubles as a personal vehicle is exactly what the cap and the business-use rule are built to limit.

The Ordering Rule: Section 179, Then Bonus, Then MACRS

Section 179 does not operate alone. There is a required sequence for first-year deductions, and contractors who do not know it leave money in the wrong place.

First you elect Section 179, up to the limit and subject to the income limitation below. Then bonus depreciation applies to the remaining basis. Then standard MACRS depreciation handles whatever is left. The order is fixed: Section 179 is elected first, bonus second, MACRS third (IRS). For property acquired and placed in service after January 19, 2025, bonus depreciation is 100%, made permanent by the One Big Beautiful Bill Act (IRS Notice 2026-11). Bonus differs from Section 179 in two ways that matter. It is not capped at a dollar limit the way Section 179 is. And it applies to whole classes of assets rather than being selected asset by asset. That makes Section 179 the more flexible tool when a contractor wants to choose exactly which purchases to expense, and how much.

The interaction is where a CPA earns the fee, because the most tax-efficient mix of Section 179 and bonus depreciation depends on the contractor’s income, the asset mix, and the plan for future years. The point for the owner is simply to know the tools stack in a set order, and that expensing everything as fast as possible is not always the smartest multi-year move.

The Trap: Deduction Is Not Cash

A deduction reduces taxable income. It does not put money in your account. This is the distinction that costs contractors the most.

Walk through a $100,000 excavator, bought outright in December to capture the deduction.

  • Buy with cash, take Section 179: You deduct the full $100,000 this year. At a 24% effective rate, that saves roughly $24,000 in tax. But you spent $100,000 in cash to save $24,000. Net, $76,000 left your business this year, and it left in December, right before the slow winter season when payroll still has to be met.
  • Finance the purchase, take Section 179: You can often still claim the full Section 179 deduction in year one (for a purchase, or a qualifying finance structure where you are treated as the owner for tax purposes), while paying for the equipment over time. You get the roughly $24,000 tax saving without the $100,000 cash hit up front. Your cash stays available for payroll and materials. The trade-off a financing decision adds: the loan is a liability on your balance sheet, which affects working-capital and debt-service ratios that sureties and lenders watch, and that can move your bonding capacity. For a contractor whose bonding line matters more than the tax saving, that balance-sheet effect belongs in the decision alongside the cash and the deduction.
  • Operating lease: You generally cannot take Section 179 on an operating lease, because the lessor owns the asset for tax purposes. You deduct the lease payments as you make them. Smaller tax benefit, smallest cash impact, most flexibility if you replace equipment often.

The lesson is not that one option wins. It is that the cash position decides, not the deduction. A contractor sitting on strong cash reserves who will keep the equipment for years may rightly buy and take the full deduction. A contractor whose cash is tight, or whose work is seasonal, can do real damage by draining the account in December for a tax saving worth a quarter of what was spent. The deduction is real, but a $24,000 tax saving does not help the business that cannot make February payroll because it bought an excavator in December.

The Income Limitation, and Why It Bites

There is a quieter limit that catches contractors mid-decision: Section 179 cannot create a loss. The deduction is limited to your taxable business income for the year, and it applies at the owner level, not just the business level (Block Advisors; IRS). If your construction business had a thin year, you may not have enough taxable income to absorb the full deduction on a big purchase, and the unused portion carries forward rather than helping this year.

This turns the December instinct on its head. The contractor most tempted to buy equipment to “wipe out” a tax bill is sometimes the one whose income cannot fully absorb the deduction anyway. The contractor with a strong, profitable year, the one who can actually use the full deduction, is also the one most able to afford the purchase. The income limitation is a reminder that the deduction is only worth what your income lets it offset. That is a number to check with your accountant before signing for the equipment, not after.

A Florida Wrinkle: State Conformity

Florida contractors get one piece of good news and one caution here. The good news: Florida has no personal state income tax, so for most owners the federal deduction is the whole story on the personal side. The caution: Florida does impose a corporate income tax, and states do not always conform fully to federal Section 179 and bonus depreciation rules. If you operate as a C-corporation, or are otherwise subject to Florida corporate income tax, confirm with a CPA how Florida treats the federal deduction in the relevant year, because conformity can require add-backs that change the after-tax result.

If You Do Not Expense It: MACRS Depreciation

Not every contractor wants to expense equipment in year one, and sometimes the income limitation or a multi-year tax plan makes spreading the deduction the better move. That is where MACRS, the standard depreciation system, comes in.

Under MACRS, equipment is written off over a set recovery period rather than all at once. Most construction equipment falls into a five-year or seven-year class, and the method is accelerated, meaning the deductions are larger in the early years and taper off later. A contractor who skips Section 179 and bonus depreciation, or who has basis left after them, depreciates the remaining cost on this schedule. The trade-off is straightforward: Section 179 and bonus depreciation pull the tax benefit forward into year one, while MACRS spreads it across the asset’s life. Pulling it forward helps the year you buy; spreading it can be smarter if you expect higher income (and higher rates) in future years, or if your current income cannot absorb a big upfront deduction anyway.

This is the other half of the planning conversation. The question is not only buy versus lease, but, once you buy, how fast to take the deduction. The fastest write-off is not automatically the most valuable one across several years. Matching the timing of deductions to the years you actually need them is a real piece of tax strategy, one a contractor should run with an accountant rather than defaulting to “deduct it all now.”

How the Pieces Fit on a Real Purchase

Put the stack together on the $100,000 excavator, bought and placed in service in 2026 by a contractor with plenty of taxable income to absorb it.

The contractor can elect Section 179 on the full $100,000, well under the $2,560,000 limit, and deduct the entire cost this year. Suppose instead he wanted to preserve some Section 179 capacity, expecting larger purchases later that year that might approach the phase-out. He could elect Section 179 on part of the excavator and let bonus depreciation cover the rest, since bonus has no dollar cap. Or if he wanted the deduction spread out, he could skip both and depreciate the excavator over its MACRS class life. Same purchase, three legitimate tax outcomes, and the right one depends entirely on the contractor’s income this year, their expected income next year, and their cash position. The equipment did not change. The tax strategy did, and that is the point: the purchase is a business decision, the deduction timing is a tax decision, and they should be made in that order.

The order of questions matters. Start with the business need and the cash, not the deduction.

Two Timing Traps: “Placed in Service” and Recapture

Two technical rules quietly undo Section 179 plans, and both are easy to walk into.

The first is “placed in service.” The deduction is available in the year the equipment is placed in service, which means delivered and ready for business use, not the year you ordered it or paid the deposit. A contractor who signs for an excavator on December 28 but does not take delivery and put it to work until January has bought a next-year deduction, not a this-year one. If the whole point of the December purchase was to offset this year’s income, missing the placed-in-service date defeats the plan entirely. The lesson: if you are buying for a current-year deduction, the equipment has to be in your possession and usable before the year closes, not just on order.

The second is recapture. Section 179 requires business use above 50%, and that test does not stop at the year of purchase. If business use of the equipment later drops to 50% or below, the IRS can recapture part of the deduction you already took, adding it back to your income in the year the use dropped. This catches contractors who expense a truck at full Section 179 in a busy year, then shift it to mostly personal use when work slows. The deduction was not permanent; it was conditional on continued business use. Equipment that genuinely stays in the business is fine. Equipment that drifts to personal use after the write-off invites the recapture rule, and an unexpected add-back to income in a year you were not planning for it.

Neither rule is exotic, but both reward a contractor who understands that the deduction comes with timing conditions attached, before and after the purchase, not just a one-time election in December.

How the Decision Should Run

Do you need the equipment for the work, regardless of tax? If not, the deduction is not a reason to buy. Will you keep it long enough to justify owning rather than leasing? Is your taxable income high enough this year to actually absorb the Section 179 deduction, given the income limitation? Is your cash position strong enough to buy outright, or does financing preserve the working capital you need through the season? Whether a specific finance or lease structure qualifies for Section 179 depends on whether you are treated as the owner for tax purposes, which is a determination to confirm with your CPA before signing, not after.

Answered in that order, Section 179 becomes what it should be: a way to make a purchase you needed anyway more tax-efficient. Answered backward, starting from “how do I lower my tax bill,” it becomes the reason a profitable contractor ends the winter short on cash.

How This Lives in Your Books

The bookkeeping side is where the strategy either holds together or quietly falls apart. Equipment you buy is a fixed asset, recorded on the balance sheet and depreciated, even when Section 179 lets you deduct it all in year one for tax. That creates a difference between your book treatment and your tax treatment that your accountant tracks, and that difference is normal, not an error. Financed equipment adds a loan liability and an interest expense that is deductible separately from the equipment itself. An operating lease is neither an asset nor a loan on your books in the same way; it is an operating expense as you pay it.

The contractor who buys equipment and never records it properly ends up with financial statements that do not reflect reality, and so does the one who confuses the tax deduction with a cash expense in the books. That matters the moment a bank or surety asks for them. Clean fixed-asset records, a clear loan schedule, and depreciation tracked alongside the Section 179 election are what keep the equipment decision from muddying the same WIP and financial statements your bonding capacity depends on.

Let the Deduction Be the Bonus, Not the Driver

Section 179 is a powerful tool and, at 2026 limits, a generous one. But it rewards a purchase you were going to make anyway, and it punishes the contractor who buys to chase the write-off and drains the cash that runs the business. Buy what the business needs, finance it in the way that protects your cash, confirm your income can absorb the deduction and that Florida’s rules cooperate, and record it cleanly so your financials still tell the truth. Do that and the deduction is a genuine bonus on a sound decision. Reverse it, letting the tax tail wag the business dog, and Section 179 becomes the reason a profitable year ends with an empty account in February.

For a Florida trade business weighing a year-end purchase, the practical work is mostly sequencing. Confirm the equipment earns its place in the operation. Choose the financing that leaves enough cash for the slow months. Check that this year’s income can actually absorb the deduction. And time the write-off, Section 179, bonus, or MACRS, to the years it helps most. Get that order right and the books stay clean enough to support a bond renewal or a bank line. That sequencing, run against your real numbers rather than a December impulse, is exactly the kind of call a construction-focused bookkeeping and advisory process is built to handle.
